My partner and I stayed at this business hotel for 5 nights. The hotel is situated close to Apgujeong station, about a straight 10 minute walk from exit #3. Easy to find. Hotel is on the left side. We booked a standard double through Agoda for about $80ish per night.
Room - clean, wall-mounted television (watch out for the porn channel), comfortable bed (harder than usual but I prefer this), bidet toilet, non-steamed mirror, good shower. Bring your own shampoo, toothbrush and toothpaste as these items are only provided upon payment. In-room wifi connection was fast and never cut out. LAN cable is also provided.
Location - close to pubs, popular club "Annex", convenience stores, bakeries (love paris baguette), 24-7 cafes, restaurants (including korean bbq), 'rodeo street' and plastic surgery clinics. The hotel is located a few train stops away from all the hustle and bustle of Seoul.
Staff - most spoke english well, helpful, attentive and professional.
